Study Notes
Classification System
- Aristotle proposed the first classification system.
- Organisms were classified into two main groups: plants and animals.
- Animals were subdivided based on movement.
Taxonomy and Classification
- Taxonomists are scientists who classify organisms.
- Linnaeus classified organisms based on their form and structure.
- The largest classification group is the Kingdom.
- Organisms of the same species can interbreed.
Origin of Life
- The earliest ancestors and most ancient branches of life are represented by kingdoms.
- The genus can be further divided into species.
Classification Hierarchy
- The seven classification groups, from largest to smallest, are: Kingdom, Phylum, Class, Order, Family, Genus, Species.
- The five kingdoms of classification are: Animalia, Plantae, Fungi, Protista, Monera.
Unicellular Organisms
- Monera and Protista are kingdoms that contain unicellular organisms.
- Monera is characterized by the absence of nuclei.
- Monerans are also known as bacteria.
Characteristics of Organisms
- Unicellular organisms consist of a single cell.
- Autotrophs are plants that produce their own food.
- Heterotrophs are animals that cannot make their own food.
Binomial Nomenclature
- The two-part naming system is called Binomial Nomenclature, devised by Linnaeus.
- Scientific names include the genus and species, and are written in italics with the genus capitalized.
Gases Preceding Life
- Gases present before the origin of life included nitrogen, hydrogen, carbon, methane, ammonia, water vapor, and carbon dioxide.
Taxonomy Science
- Taxonomy is the science of naming and classifying organisms.
- Homologies indicate that related organisms share similarities from a common ancestor.
Characteristics by Kingdom
- Animalia: Eukaryotic, multicellular, heterotrophic (consumers).
- Archaea: Single-celled prokaryotic, can be autotrophic or heterotrophic, often decomposers.
- Bacteria: Prokaryotic, unicellular, can also be autotrophic or heterotrophic.
- Fungi: Eukaryotic, mostly multicellular, heterotrophic, primarily decomposers.
- Plantae: Eukaryotic, multicellular, autotrophic (photosynthesis).
- Protista: Eukaryotic, unicellular or multicellular, can be decomposers, consumers, or producers.
Fossil Evidence
- Examination of fossil skulls can help determine ancestral lineages of animals.
Classification Terms
- Phylum is utilized for animals, while division is the plant equivalent.
Miller-Urey Experiment
- Stanley Miller and Harold Urey mixed ammonia, methane, and other gases in their experiment related to the conditions of early Earth.
